Amazon Elastic Container Registry提示：denied: Not Authorized-马春杰杰

利用Docker上传镜像时，突然出现：denied: Not Authorized：

[opc@instance-20240410-1646 aws_docker]$ sudo docker push public.ecr.aws/f6t4a9n0/machunjie_docker:latest
The push refers to repository [public.ecr.aws/f6t4a9n0/machunjie_docker]

[opc@instance-20240410-1646 aws_docker]$ sudo docker push public.ecr.aws/f6t4a9n0/machunjie_docker:latest

The push refers to repository [public.ecr.aws/f6t4a9n0/machunjie_docker]

一开始我以为是IAM权限的问题，不过仔细分析之后发现，这根本就没到Amazon那边，直接本地就无权限，那问题就出在Docker身上了。试了一下，果然：

[opc@instance-20240410-1646 aws_docker]$ docker image ls
permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Head "http://%2Fvar%2Frun%2Fdocker.sock/_ping": dial unix /var/run/docker.sock: connect: permission denied

1 2	[opc@instance-20240410-1646 aws_docker]$ docker image ls permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Head "http://%2Fvar%2Frun%2Fdocker.sock/_ping": dial unix /var/run/docker.sock: connect: permission denied

root账户可以正常访问Docker，但是opc不行，这也简单，只需要把/var/run/docker.sock的权限提高就行，比如777：

sudo chmod 777 /var/run/docker.sock

然后再试试push：

[opc@instance-20240410-1646 aws_docker]$ docker push public.ecr.aws/f6t4a9n0/machunjie_docker:latest
The push refers to repository [public.ecr.aws/f6t4a9n0/machunjie_docker]
